The official site lists a May 27 release date for the Wii sequel, putting it near simultaneous with the overseas versions. Pricing is set at ¥5,800.

Other specs mentioned at the site include 2 player cooperative play, three save data slots, and controller compatibility exclusively with Wiimote and Nunchuck. All of this should be expected for those who played the original.

The site is currently sparse, with just one section titled Mario Flies off to Space.

Mario heads off to a variety of plans in search of power stars, writes the page. He's got Yoshi with him this time. Yoshi can suck up enemies and perform extended jumps, similar to his abilities in past Mario games.
